Over-voltage Protection

[Robert Ritchey]

Hi,
I have a question about protecting a circuit from an overvoltage condition. We
have a new device that we are planning to use a regulated 5V wall-wart type
device for power. They have also requested overvoltage protection in case
someone plugs in a 6V or 8V unregulated supply by accident. My expertise
is mostly digital so I am not sure what the best and cheapest way to do this
would be. Thanks in advance for any help or pointers.
